Description
External safety contact open
Outdoor sensor contact open
(not connected)
Maximum average T of supply
and return sensor for central
heating is repeatedly exceeded.
Operation is normally possible
for the hot water supply during
the block. The pump continues
to operate at minimum capacity
during the block.

Incorrect parameter setting for
the minimum or maximum power
A temperature difference has
been detected between the
supply and return sensor whilst
the burner is not in operation.
After the average T has
disappeared, the block will
disappear.

no water fl ow can be detected
through the controller. De-aeration
cycle is started. When water fl ow
is detected during this cycle, the
de-aeration cycle is terminated
and the burner is released.
The controller checks the water
pressure during static and
dynamic situation.
The frequence of the power
supply deviates more than + or
-1.5Hz
An error, which has been detected, is indicated on the display by a block message.
Blocks can be temporary in nature. The controller will do everything possible to prevent
a system lock and temporarily switching off the boiler as a result of a block. Please
see below for a summary of blocks.

Solution
Rectify error as a result of which by determining contact is open.
Or repair interconnection between 24/25
Rectify error as a result of which by determining contact is open or outdoor
sensor is not connected.
Connect outdoor sensor or repair wiring (position 18/19) or replace outdoor
sensor.
Check fl ow through the installation.
See the installation instructions for the hydraulic connections to the boiler
(3-Way-Thermostatic valve, Plumbing Kit installed?)
Possible causes: (radiator) shut-off valves closed or blocked water fi lter
Activeted room sensor (RS101) in non leading room (closed thermostatic
radiator valves?) Check pump height.
Check minimum and maximum Temperature difference in Parameter Step
46 + 47.
Check fl ow through the boiler and DHW tank
See the installation instructions for the hydraulic connections to the boiler
Possible causes: (radiator) shut-off valves closed or blocked water fi lter
resistance (coil) in tank to high (see pump height)
Check 3-way-valve on function and pollution.
Call Rinnai
Check the supply and return sensor for the resistance value and replace
the defective sensor
Check the installation for any external heat source and rectify this
Check vent system
Call Rinnai
Call Rinnai
Check vent system
or check parameter 84 for default
- check the installation for the presence of air;If there is a secondary
pump installed and it is not hydraulicly separated, it could cause pres-
sure differences.
- check the use of balancing valves
check if the pump is functioning and/or that the water pressure sensor is
working properly;
Polluted pump; Polluted water pressure sensor; Polluted water fi lter;
Wiring of pump.
check the main power supply
